WOW. Just Decided to Check out how much my GC Collection is worth

[Skullwaker]

Nintendo games more often than not go up in value over time. I've noticed this is especially the case for the consoles that didn't quite sell well (N64 and GCN namely).

Watch out, in 5-10 years I can see many Wii U games going for a lot of money (some already are).
